In this paper we study the generation of coherent terahertz phonons in a double-barrier heterostructure (DBH) under the influence of an external applied bias. The system is characterized by an energy difference between the two lowest levels in the we

In this paper we propose a device capable of generating ultra-high-frequency coherent sound. It is called SASER by analogy to laser. The device consists of a double barrier heterostructure (DBHS) tailored to permit phonons to resonate with the electr

Resonant tunnelling in a double-barrier heterostructure (DBHS) designed in order to produce an intense coherent emission of phonons is studied theoretically. Thisemission is achieved when the energy difference between the first excited level and the

We investigate a new device, a SASER, consisting of a double-barrier heterostructure (DBH) designed to generate ultra-high-frequency coherent sound. The device is tailored such that under the influence of an external bias, some of the electrons injec
